This is the way!
Yes, our Fiat based system causes most of problems we see and experience today.
But a total collapse would be horrible.
Bitcoin could be there to help rebuild everything. But only if the collapse does not wipe out too much. In some of the scenarios some people draw out there, Bitcoin wouldn't be your first priority anymore. Your focus would be on how to survive the next couple of days, if not hours.
I don't want to focus on such scenarios.
A slow, somewhat predictable migration would be much more healthy.
It will still cause a lot of headaches. Not doubt about that.
